Professional Quality Blocks Professional Quality Blocks - High strength control Roshield wax bait blocks are manufactured by a hot casting process, ensuring the wax and other components are intimately mixed. This process ensures blocks are highly tolerant to humidity and suitable for use both indoors and outdoors. In addition, the blocks have a hole through the centre that allows them to be securely fixed in a bait station. Blocks are the first choice for most pro operators as they can be used within damp environments such as sewers, cellars and external bait stations.
